A food pyramid is a very simple way of looking at a bigger picture called a food web. A food web is made up of all the different plants and animals that have an effect on one another by their feeding habbits. A group of food pyramids meshed together make a food web. What exactly a food web tries to proove is that if even one thing becomes extinct in a food web it will have a big impact on all the other animals that are a part of that food web as everything works step by step.
Why Does A Food Web Give A More Accurate Picture Of The RelationshiPs Between Organisms In An Environment
Because the food web contains2 and more food chains
12" is a good rule of thumb for 2-hour rating....but the 2006 IBC will give you a more accurate indication, plus industry web sites for concrete vendors will give you more accurate info.....
the difference is that a food chain is smaller then a food web because a food web is more animals then a food chain
From a food web you can see which animals eat others, it is a lot like a food CHAIN but a web shows lots more animals, and can be more complicated.
From various places such as the web and libraries - the links below will give you a starter on information.
Pesticides are cumulative, so the animals at the end of the food web have more of them.
Food webs and food chains are different things, but a food web is a more accurate representation of most animals' diet. A food chain is simply a line of one of each type of animal, so it might have one producer, one primary consumer, one secondary consumer etc, whilst a web is more complex, and represents more animals. For example: Food Chain: Cabbage-->snail-->Thrush-->sparrowhawk Food Web: http://www.bigelow.org/edhab/fitting_algae.html (pictures and more info here)
this web site dosent give good info on delaware
Sikhs worship in a gurdwara. For more info web search it!
No I can't because white tigers are endangered and they have changed the food web of white tigers and they're in captivity.
The answer depends on what you would like to know. If you want to know how diverse an ecosystem is, then you need to look at the food web. This will also show you the feeding relationships between all the species in the ecosystem. If however you are interested in how efficient energy transport is in a system, or would like to know how stable a system is likely to be, a food chain is going to give you a better idea. In short: Food Webs give you a bird's eye view of all the species in the system you are studying. Food Chains give you a single pathway that indicates how many trophic levels there are in a food web.
